Parrish333,
They are a lot of army users of the SIG 550, mainly warm countries, for the SIG 551: Brazil, India, Indonesia, Macau, Malaysia, Malta, Spain... Only few rather cold and or mountaineous countries: France, Poland, Slovakia... They are much more police, boarder corps and other law enforcement, for example the FBI, DEA, some canadian police corps, same in Finnland, Germany, Argentina. I was sure that the US Marines and Navy SEAL's had some, but could'nt find sources to confirm. So, thank you

, but I have now to choose: hopeless finding a 1/18 french Puma/Cougar helicopter (our multipurpose helo in Switzerland) or changing my guys guns for the M4. And re-shot this difficult pic!
In the Sahara dio, all vehicles are 1/18 die-cast. The green UN forces jeep is the chinese BJ2022, I think it is a development of the chinese rebuilt of your HUMVEE. I could'nt find any 1/18 Toyota pick-up, the mostly used vehicle within subsaharian countries (revolutionnary groups and regular armies) as we can see now in Mali with the TV news. A guy in this board found a simple and toyish one, better scaled than the Bruder's, but I couldn't find any on eBay. The Ford F-150 could be an alternative, haven't got any untill now (price incl. shipping: 1 BJ2022= 2 Ford F-150). Of course, it's usually not possible to put a 1:18 figure in an 1:18 die-cast vehicle without removing the legs or seats, so 1:16 is a solution, but less realistic. Well, for the Foxhole Contest, I had only few weeks to make and send some pics, and I made with what I have.
